1. Introduction
After I have designed the solution for the Assignment 1 situation. In Assignment 2, I will demonstrate how to apply procedural programming in solving the scenario. I will use C language to create the best possible software that I have learned after taking Procedural Programming. Actually, when I did assignment 1, I wrote a program that met the requirements, but it was not very good when I could not separate the code in the main () function into functions. However, in this Assignment 2 I have overcome that. In addition, I have made an extra step so that users have to log in to use the program and I also created a few functions that are quite useful in managing students' grades. In this assignment, I will present in 2-chapter as: Chapter 1: Implementation and explain program Chapter 2: Test Plan
2. Chapter 1: Implementation and explain program
2.1 Scenario:
A math teacher wants to manage grades of a class. He asks you to help him to write a small application to do that. He needs to enter student IDs, studentās grades and store these information into 2 separate arrays (integer array for IDs and float array for grades). Then he needs to print all student IDs together with their grades. Finally, he needs to know which student has highest grade and lowest grade. Your program should be menu based with the options above. When an option is done, the program should go back to the main menu so he can choose another option. There should be an option to quit program. The following is a program that I created to respond to this situation and it also has a few more interesting features. I'll break it down into important pieces of code so that it's easier for people to understand my program.
When going to each function, I will explain more about how variables are used in the operation of the program.
2.3 Functions
2.3.1 Function login Figure 3 - Function login A new function compared to my assignment 1. This is a feature I find very interesting and I have invested a lot of time in reading documentation and writing code. This function has the ability to require the user to enter the correct "loginname (admin)" and "password (123456)", then the program will start showing the
main interface for users to use the program. This function is written based on the endless loop āWhileā to ask the user for correct input and the function āstrcmp(string compare) ā information, the program will print the message "Login success".
